IGNITION DEVICE.

Specification of Letters Patent.

Patented Jan. 6, 1920 Application filed October 13, 1917. Serial No. 196.371.

State of South Carolina, have inventedcertain rnew and useful Improvements in Ignition Devices, of which the following is'a had to the accompanying drawing.

The invention relates to new and useful mprovements in ignition devices, and more particularly to an ignition device including ignition electrodes, a generator electrically connected .to the electrodes and atrip-operated spring-actuated device for said electrodes.

An object of the invention is to provide a two-part supporting bracket for an ignition device of the above character, wherein the electrodes'and the trip-operated spring-aetuated mechanism for thegenerator and elec trodes are carried by one part ofthe supporting bracket, while the generator alone is carried by the'other part of the said bracket. w

A further object of the invention is to provide a supporting bracket of the above character, which is so constructed that the supporting part for the generator together with the generator may be removed without disturbing the electrodes and the trip-operated spring-actuated mechanism, so that a battery maybe used for supplying current to the electrodes for ignition.

A further object of the invention is' to provide a supporting bracket for an ignition device of the above character which may be cheaply manufactured.

a In the drawings which show by way of illustration one embodiment ofmy invention,-' I

'Figure .1. is a side view of a supporting bracket embodying my improvements, with the gene1ator,-the electrodes and the spring- 'actuated mechanism therefor mounted there- Fig. 2 is a front view ot the same with the porting Fig. 3 is a plan view of the su ectrodes bracket with the generator, the e andthe actuating mechanism removed.

The invention broadly consists of an ignition device including a two-part supporting bracket. On one part of the supporting bracket is mounted an ignition electrode and .wall into the cylinder.

the trip-operated spring mechanism which operates the generator, while on the other part of the bracket is the generator. The part of the bracket which supports the generator is carried by and projects from the part of the bracket which supports the electrodes and the actuating mechanism. This permits the generator and the supporting partof the bracket therefor, to be readily removed in case the bracket is broken, or when the generator is to be repaired and a battery used to supply current to the electrodes.

Referring more in detail to the drawings, my improved ignition device consists of a two-part supporting bracket porting bracket consists of the part 1, which is adapted to be attached to an engine cylinder by means of stud bolts passed through openings 3 and 4. Suitable nuts are threaded on to these bolts andclamp said bracket against the engine cylinder. The part 1 of the bracket is provided with a sleeve 5, which projects through an opening in the cylinder Mounted in this sleeve 5 is a fixed electrode 6, and a movable electrode 7. The electrodes are provided with ignition points 8 and 9 respectively.

. at one end againstsaid arm and its'other end agalnst an abutment 12; this spring shifts the movable electrode so asto nor mally hold the ignition points in contact.

Also mounted on the part 1 of the supporting bracket is the trip lever 13. Said bracket is provided with a rigid heairingld, which carries the trip lever. Said trip lever is formed with pins 15 and 16. A spring 17 engages at one end the pin 15, and at its other end a pin 18, carried by the bracket part 1. the pin 16, and at its other end pin 20, also carried by the bracket part 1. This trip lever is actuated by a trip finger 21,'which is S. Said sup- The spring 19, engages at one end The bracket part 1, is formed with strengthening webs or ribs as clearly shown in the drawings, so as to provide a very rigid support for the spring-actuating mechanism. The lower portion of part 1, of the supporting bracket is faced and adapted to receive and. support the projecting part 2 of said supporting bracket. The part 2 of the supporting bracket has a downwardly depending flange 2%, which is provided with suitable openings to receive the bolts and 26. These bolts are threaded into suitable openings in the supporting part 1 of the bracket. The SUPpOlftlng part '2, of the bracket is in form of a shelf on which the generator indicated at G rests. Suitable bolts 26, passup through openings in the shelf and are threaded into the base of the generator.

The flux shifting; member of the generator is provided with a forked arm which is adapted to engage the pin 15, so that the movements of the trip lever are in'iparted to the flux shitting member and thereby a current is generated for ignition. shitting member is electrically connected to the ignition electrode.

From the above it will be apparent that I have provided a supporting bracket which is very strong and durable and which can be cheaply made. Part 1, may be of cast metal, while par 2, may be of either cast or stamped metal and readily attached to part 1. It will also be noted that not. only the electrodes but the trip lever and actuating springs are carried by part 1 of the supporting. bracket so that the supporting part 2 for the generator may be removed without interfering; with the operation of the trip mechanism and the actuation oi the movable electrode. This enables the generator and also the supporting shelf sup- )()I'tl11, 1' the same to be temporarilyremoved and out of the way and at the same time current. may be supplied from a battery for furnishing ignition. Then again, the projecting shel't' which carries the heavy generator may be broken. By my improved c mstruction the shelf may readily be replaced without necessitating the replacement of the entire supporting bracket. It will shelf for the generator.

It is obvious that minor changes in the details of onstruction and also the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appendedclaims.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. An ignition device comprising a two part supporting bracket, ignition electrodes carried by one part of said bracket, a generator carried by the other part of said bracket, and a trip operated spring; actuating device for said generator and electrodes carried by the part of said bracket supporting the electrodes.

2. An ignition device comprising atwo part supporting bracket, one of sai parts being in the form of a shelf carried by and projecting from the other part of said bracket, agenerator m unted on said shelf, a fixed and aunovable electrode carried bythe part of the bracket supporting the shelf, actuating devices for said generator and said movable electrode carried by the part of the bracket supporting the electrodes.

An ignition device comprising a twopart supporting bracket, one of said parts being in the form of a shelf carried by and projecting from the other 'part of said bracket, a generator mounted on said shelf, a fixed and a movable electrode carried by the part of said bracket supporting the shelf, a trip lever and actuating springs therefor, carried by the part of the bracket supportinv the electrodes, and means whereby said trip lever actuat-es the generator and movable electrode.

In testimony whereof I hereunto atlix my signature.
